[Bug 630748] [NEW] iwlagn degrades quickly during normal wifi session

[Nick Moffitt]

Public bug reported:

I recently upgraded my lucid laptop (thinkpad X200s) to maverick.  I
found after the reboot that my wireless degrades after about 8 hours of
ordinary use.  I had 45% packet loss direct to my WAP, and this was
easily cleared up by doing "modprobe -r iwlagn; modprobe iwlagn" as
root.

I'd not be so quick to file this except that Paul Collins told me that
he'd seen the same behavior from upstream 2.6.35.
